OPTIMAL UTILIZATION OF HYBRID WIND-SOLAR SYSTEM AS DVR FOR VOLTAGE REGULATION AND ENERGY CONSERVATION

摘要

This paper presents a novel optimal utilization of hybrid wind-solar system as dynamic voltage restorer (DVR) for voltage sag, voltage swell, outage and unbalanced voltage mitigation. Besides the voltage regulation, the proposed DVR reduces the energy consumption from the three phase utility grid by utilizing the rated inverter capability after excessive or equal real power generation to the load demand during both day time and night time. It reduces the energy consumption from the three phase utility grid. However, the reduction of energy consumption is always desirable for the reduction of panel tariff and electricity demand. The proposed system was simulated using MATLAB-SIMULINK in which the input parameters were selected from the metrological data of the selected location to validate the advantage of the proposed system.
